T0 all w hom t may concern Be It known that I, R101-IARD D. GAD

Laer-IER, a citizen of the `United States,re-

siding at Chicago7 in the county'otjCook and State of Illinois, haveinvented certainA new and useful Improvements in Derails, of which thefollowing is a specification.

My invention relates to derails, and particularly to a portable derailwhich is selflocking and which is designed to protect repairmen workingon cars on the line tracks, as well as to serve as temporary signalunder unusual circumstances.`

An object of the invention is to provide a derail which may be readilyportable, selfconta'ined, and which kmay be quickly and securelyfastened to a track rail,

Another object ot the invention .is toiprovide a derail which may betemporarily and quickly applied to a track rail and locked thereon.

A further object Ot the inventionis to` provide a portable derail which.may bel A still further object 'of the invention isy to provide aportable derail adapted to be secured in position by a clamping actionand a member projecting inthe path of a car operable. in the directionof lmovement of the saine for increasing clamping engagement. y i

A. still further objectot the invention is toimprove portable derailsfor successful commercial use.

The above recited invention will be apparent from. the followingdescription and drawings and will be particularly pointed out inappended claims:

in the drawings: 1

Figure 1 is a side elevation `oi the derail of my invention. y

Figure 2 is a top plan view ofthe same.

Figure 3 is an end-g elevation looking from the left hand end of Figure1', and y Figure 4C is the preferred forni of target used as a handlefor operating the clamp as well as serving as a signal.

In the drawings 5 is a standard T traclr` and other objects of theadapted to be temporarily mounted. `The derail comprises a casting"having a substantially flat undersurface 6, which rests on thehead'offthe rail and depending side flanges and 8 for maintaining the positionof the casting on the rail. The upper surface of the derail casting isprovided with a tread 9 for the car wheel which has been displaced, andan upstanding lange l0 defining aA groove 111 in which the flange of thewheel is received. ln elevation the tread 9 hasv an' upwardly inclinedportion 9 and a Hat portion 9b, the height oi which is suttin cient tocarry the ange of the wheel over the top of the rail. As will be notedin lligure 2 the tread and groove extend diagonally across the castingso as todirect the wheel oil' ot, the tracin'` 'or purposes wellunderstood. The casting has a. stirrup' integral therewith and dependingon ones'ide of the casting asat 12, andhaving an upturnedportion 13. Thedepending portion 12 `is provided with vertically disposed cylindricalrecesses 14 and 15 for receiving stub shafts 16 on. a cam menfiber '17The cam member 1T is adapted to he horizontally moved about the verticalfazris formed byy the stub shaft 16, which cam has a cam surface 18adapted to be wedged against the web of the rail as `is shown in dottedlines in Figure 2 and in full lines in Figure 3. The cam has a bevelsegment 19.y ln the upstanding portion 13 *of the `stirrup there ismounted for rotative movement in a vertical plane a toothed segment 20which when in position is in mesh with segment 19 of the cammember 17;member 20 is sup-portedin horizontally disposed journals 21. and 22.Extending upwardly -trom the member 2O is a handle 28 which in thepresent instance comprises a tube 24 carrying at its upper end atarfYetQ. on which any desirable legend such as Stop may bev applied.The handle 23 and the cam 17 are sov arrruiged that when inunlockingposition the vlifuudle is down, that is,` the cam 17 is swungaway from com tact against the 'track web and in position to permitapplication and removal ot the derail with respect to the track rail.y

In applying the derail to Athe track rail at any point, the handle 24 ismoved downwardly into a substantially horizontal position, whereupon thecasting is placed on the ball ofthe rail and the handle then raised tosubstantially vertical position. ARaising `the handle will by reason ofthe interincshiiig of the njieiiibers 2O and 17 cause the cam tobeyswung against` the web of the rail and held securely vthereagainst. Byplacing the handle onthe inside of the derail any'car moving on thetrack and striking the same Would increase the pinoli of the cam againstthe web` of the rail, and thus prevent dis# the derail against removalby an'un'autliorized person. y

vIt Will be observed that my invention provides ixquick-locking,portable derail Which may be quickly applied and removed anywhere alongthe track rail and Which `is positively locked in applied position. Itisdesigned to protect the men Working under and. about cars on line tracksyor inrepair yards Where suitable provision is not made to protect theWorkmen. lt is light; therefore, readily portable and kWill lit any railsection. It isso made that a caraccidentally moved against it wouldincrease thezcam vaction rather than decrease the same, and henceeliminates the dental displacement. w

l/Vhil'e l have describedinore orless precisely the detailsofconstruction of my invention I do notwvish to he lunderstood as limitingmyself kthereto as l" contemplate changes in form and proportion ofparts and theA substitution of equivalents as circumstances may suggestor render expedient` Without departing from the spirit of my invention.

l claim: v .v I 1. A derail includinga casting adapted to Arest on arail head, a cam associated' there- 'With for eno'aoin `the rail saidcam ada ted to swing about a vertical axis and Ahaving atoothed-portion, a member carried bysaid casting and-disposed in angularrelation to 4said cam and laviig` a toothed portion for` meshing ,with`said cam, and aliandl'e connected to saidmeinber for actuating saidcam. i z i v 2; A portable, derail including a casting having a suitablyanged upper surface and possibilities of acci-l` iasaoec an undersurface adapted to rest on a rail out'of engagement with the rail Web.

A portable derail including a casting f having a suitably ianged uppersurface and an under surface. adapted to rest onA a rail head, adepending lyoke, a cam `carriedgin said: yoke adapted for contactwiththe rail web under vcertain conditions, and another member also carriedby said yoke atan angle -to said cam :for moving the same into .andl
